The effects of pre-IPO corporate activity on newly-public firms' growth

We investigate firms' pre-IPO corporate activity. We find that firms involved in extraordinary – i.e., beyond momentum – amounts of acquisitions, JVs, and alliances in the year leading up to their IPOs (1) are more likely to engage in post-IPO corporate activity; and (2) enter into their first post-IPO transaction twice as fast as other firms. Our results indicate that signaling via extraordinary corporate activity can have a significant effect on entrepreneurial firms’ growth. The implications are discussed.     

Information and communication technology adoption in micro and small firms: Can internet access improve labour productivity?

The rapid spread of information and communication technologies (ICT) may increase firms’ productivity with important consequences for job creation and for economic growth. This article contributes to this discussion by analysing the impact of internet adoption on labour productivity and the mechanisms shaping this relationship in Peruvian micro and small manufacturing firms over the period 2011–2013. The article estimates a reduced form where labour productivity is a function of internet adoption and other explanatory factors. Internet adoption is instrumented using a measure of the availability of financial opportunities for micro and small firms in Peru. Findings indicate that internet adoption: (a) increases firms’ labour productivity; (b) reallocates employment away from temporary administrative workers and non‐remunerated workers and expands employment of permanent production workers; (c) leads to the formalization of labour relationships, to the implementation of new organizational practices and to the improvement of training measures. While changes in employment and formalization of workers are linked to labour productivity gains, increases in training measures and organizational changes do not generate any additional productivity increase. Policies oriented to promote the adoption of ICT in micro and small firms can be beneficial to close the productivity gap with larger firms in Peru. Moreover, policies directed to the formalization of the workforce can provide an extra benefit, i.e. additional labour productivity gains in firms adopting the internet. Finally, policies oriented to the development of digital skills are also important to ease the re‐employment of those workers losing their jobs and the achievement of additional productivity gains that new organizational practices can provide.     

Rape culture,misogyny, and urban anxiety in NH10 and Pink

One of the most pervasive aspects of Delhi’s post-liberalization psychopathology has been everyday violence against women. The city’s rape culture was given an exceptionally sharp global focus after the horrific gang rape of Jyoti Singh on December 16, 2012. Recent Hindi cinema has begun to engage with some aspects of the capital’s misogynist urban ethos. In this paper, I look at how the Delhi subgenre of the “multiplex film” has engaged with rape culture, misogyny, and urban anxiety through a close textual and discursive analysis of two recent films—NH10 (Navdeep Singh, 2015) and Pink (Aniruddha Roy Chowdhury, 2016). Specifically, I identify how the December 16 “trigger event” and Delhi’s notorious misogyny are finding newer modes of representation through the interplay of genre and exhibition space. In what ways do these films position and imagine the “multiplex viewer”? New engagements with the figure of the consuming middle-class woman and the public discourses that surround her sexual safety and navigation of space have taken a central position in understanding the present urban psychosis of the capital. I suggest that these films and the forms of spectatorial identification that they privilege are intricately linked to the gendered spatial politics of the multiplex.     

基于委托代理理论的会计信息失真问题研究

会计信息失真问题越演越烈,并且已成为一个世界性难题。可靠性、真实性、相关性是会计信息质量的生命,但一系列会计舞弊行为的发生已篡改了会计信息的本来面目,会计信息"诚信工程"摇摇欲坠。造成会计信息失真的原因有很多,就此,我国也采取了相应的措施予以治理,但效果并不显著,往往是治标不治本。本文从产生会计信息失真问题的根源出发,重点剖析了在以委托代理理论为根基的现代股份制企业中会计信息失真的原因,并提出了提高委托代理制度下的会计信息质量的相应对策。     

Percentile Related Bounds and Estimator for the Mean of the Negative Binomial Distribution

Upper and lower bounds are obtained for the mean of the negative binomial distribution. These bounds are simple functions of a percentile determined by the shape parameter. The result is then used to obtain a robust estimate of the mean when the shape parameter is known.     

Inference of non-centrality parameter of a truncated non-central chi-squared distribution

Non-central chi-squared distribution plays a vital role in statistical testing procedures. Estimation of the non-centrality parameter provides valuable information for the power calculation of the associated test. We are interested in the statistical inference property of the non-centrality parameter estimate based on one observation (usually a summary statistic) from a truncated chi-squared distribution. This work is motivated by the application of the flexible two-stage design in case–control studies, where the sample size needed for the second stage of a two-stage study can be determined adaptively by the results of the first stage. We first study the moment estimate for the truncated distribution and prove its existence, uniqueness, and inadmissibility and convergence properties. We then define a new class of estimates that includes the moment estimate as a special case. Among this class of estimates, we recommend to use one member that outperforms the moment estimate in a wide range of scenarios. We also present two methods for constructing confidence intervals. Simulation studies are conducted to evaluate the performance of the proposed point and interval estimates.     

Implementation of just-in-time methodology in a small company

This paper describes the implementation of JIT in a small manufacturing company and the benefits that resulted for the company's operations. Preliminary analysis identified various problems in the existing manufacturing operations. The pre-implementation and post-implementation conditions of the company arc detailed. The achievements of the JIT implementation included a reduction in material traversing, reduced lead limes and inventories leading to an overall reduction in the cost of manufacturing. A smooth flow of material from the raw material stage to the finished product stage was established. Three separate product lines were combined into a flexible manufacturing assembly line. With the adoption of a holistic approach to JIT implementation, it was found that even a small company can make significant strides towards world class manufacturing status. The experience gained by the company can encourage and benefit other small companies to embrace the JIT approach.     

中国绿色GDP核算实践：问题与对策

绿色GDP核算在我国仍处于探索阶段，通过对东部、中部、西部的实际污染治理数据进行分析，指出越是GDP低下的地域，实际污染治理支出占GDP的比重越高。绿色GDP核算面临着基础数据、核算技术等方面的难题。最后，提出了现阶段绿色GDP核算应量力而行；在企业中推广环境管理体系、企业年度环境报告书制度和企业环境会计核算等对策。
